The avb custom key blocks the reboot. After I had unlocked the bootloader again, /e/OS-T started without failure.


INFO

Then I installed iodéOS 5.2 (7/2024) on the same device. There, the avb custom key is integrated in the CustomROM and does not have to be installed separately. The Pixel 4 (flame) started flawlessly with iodéOS 5.2 and the bootloader locked again - just as it should be.
